@bertolino Please include the title of the game in the thread title, otherwise we may offer hints to the wrong game.
I think what you ask of may point to Jake's Very Last Journey (https://www.adventuregamestudio.co.uk/site/games/game/2387-jake-s-very-last-journey/),
though I may be mistaken.You can find hints in this thread. (https://www.adventuregamestudio.co.uk/forums/hints-tips/jack-s-very-last-journey/#new) Please update this thread with the name of the game included in the Subject line for the first post. Let us know if this was the game you want help with or not, and whether or not you found what you were looking for in the thread I linked above.
